48-400 Black Metal Threaded Caps with Pulp & Poly Liner
Metal threaded caps are compatible with continuous thread (CT) containers and are not compatible with a lug finish. Caps include a pulp & poly (PE) liner which consists of a white pigmented, HDPE layer with a gloss finish and polystyrene backing. Liner provides reseal and good barrier to moisture and moderate barrier to oxygen. This chemical resistance works well with low-acid (inert) products as well as oil and water-based products. Not recommended for active hydrocarbons or bleaches.
